The role of the four-column hydraulic press for the traditional stamping process

Compared with the traditional stamping process, the hydroforming process of the four-column hydraulic press has achieved more and more in the automotive industry in terms of reducing weight, reducing the number of parts and molds, improving stiffness and strength, and reducing production costs. many applications.

1. Reduce quality and save materials

For typical parts such as automobile engine brackets and radiator brackets, the hydroformed parts of the four-column hydraulic press are 20% to 40% lighter than stamping parts; for hollow stepped shaft parts, the weight can be reduced by 40% to 50%.

2. Reduce the number of parts and molds and reduce mold costs

Hydroforming parts usually only need one set of molds, while stamping parts mostly require multiple sets of molds. The number of hydroformed engine bracket parts has been reduced from 6 to 1, and the number of radiator bracket parts has been reduced from 17 to 10.

3. It can reduce the amount of welding for subsequent machining and assembly

Taking the radiator bracket as an example, the heat dissipation area is increased by 43%, the number of solder joints is reduced from 174 to 20, the number of processes is reduced from 13 to 6, and the productivity is increased by 66%.
